This is a burgundy Plato 66 lever-fill pen from India dated 1961 on the barrel imprint. Plato was a brand of the Mhatre Pen Plastic Industries Private Limited which was incorporated in 1951. The external design is very similar to the UK Parker Duofold Maxima, introduced in 1958. It is an easy to service lever fill pen where the section unscrews from the barrel, giving quick access to the ink sac. The metal parts are gold plated, with a quite bright yellow gold. The stainless steel nib is lightly gold plated and stamped SUPER QLTY PLATO TIPPED. It's 5 1/8 inches long and the barrel imprint reads PLATO "66" over REGD. over MADE IN INDIA over 1961. Mhatre stamped almost every part of the pen with the PLATO brand, including the clip, section, lever, barrel and nib.
